H-Drol dosage and cycle length

Curious as to the ideal dosage and cycle length for 2 bottles of H-drol on a bulk. Many of the logs I see vary wildly in dosage and length although 50-100mg for 5 weeks seems pretty popular. Im not concerned about shutdown as I intend to run both Clomid and Nolva (and its H-drol ) but other sides are, of course, a concern. I was thinking 6 weeks at 50 or 75mg. Thoughts? By the time I run this cycle it will likely be my second PH but I am still a virgin right now. Thanks.
